I connected to an MS Access 2007 database table using Tableau v6.1 using the "Import all data" option.
If I add or alter the MS Access table and then select Data->Refresh in Tableau, will the updated data from my MS Access table appear in Tableau?
I ask because I suppose the alternative would be to create a new .tde file every time I make an update to the MS Access table.
If you have imported all data, then you have created an extract, i.e. the data is stored internally in Tableau. If you make changes to your Access database, you need to do Extract -> Refresh to update your views.
